Synthesis and properties of lead iodide for perovskite solar cells

  • 摘要: 碘化铅是有机无机杂化钙钛矿太阳能电池的关键原料,其使用方法为溶解在二甲基甲酰胺(DMF)中然后制成膜.碘化铅在DMF中的溶解性对电池器件的性能有重要影响.本文经实验判断,造成碘化铅在DMF中溶解性差的原因是H2O、PbO、PbO2等氧化物在碘化铅晶体表面形成氧化物薄膜,阻碍其溶解.在一定范围内,碘化铅在DMF中溶解性取决于碘化铅合成过程中反应溶液的pH值.经过扫描电镜、X射线衍射、X射线光电子能谱等分析检测,确定有机无机杂化钙钛矿太阳能电池用碘化铅最佳合成pH值为2;且在一定范围内反应溶液pH值、滴速和溶液浓度不会影响碘化铅的微观形貌及其在DMF中的溶解性;同时发现重结晶、热反应以及慢滴速反应条件会使碘化铅样品在(001)面择优生长.
